【摘要】 伴随着世界工业的发展和对能源需求的增加,石油工业的作用日渐突出,为了能将有限的石油资源充分的开发利用,就必须提高钻探技术。在钻探过程中起着极其重要作用的钻井液技术也面临着全新的挑战,这就要求石油工作者要积极开发新的钻井液处理剂,以满足钻井液处理剂越来越高标准的技术要求。本文从如何充分合理利用石蜡资源和满足钻井作业需求的角度出发,对石蜡乳化技术进行了研究,研究了乳化温度、乳化时间、搅拌速度、液相粘度、表面活性剂的作用等对石蜡乳化的影响,利用激光粒度分析仪对乳化石蜡进行粒度测试,其粒径分布范围在0.1-1.0μm之间,具有很好的稳定性能。同时研究了产品对钻井液密度、流变性能、滤失量、润滑性能和页岩抑制性能的影响进行了评价和分析。并对其作用机理进行了深入的探讨和分析。实验结果表明:本文研制的乳化石蜡对钻井液的密度和流变性能影响极小,同时具有很好的润滑效果和页岩抑制效果。当其在钻井液中的加量为2.5%时,其粘附系数降低率为50%;页岩膨胀降低率为28%。通过实验中乳化石蜡所表现出的性能来看,该处理剂具有很好的应用效果,达到以致超过了国内同类产品的水平,不失为一种优秀的钻井液处理剂。更多还原

【Abstract】 With the development of world industry and the increase of the energy demand in the world,the effect of petroleum industry will more and more important. In order to exploit the limit oil resource,we must enhance the drilling technic. As the same time,the drilling fluid technic which take very important effect in driling face a new challenge. This demand oil operator exploit new drilling agent and content the high standard of drilling fluid agents.With the opinion of effective utilization of the paraffin resource and satisfying the demands of drilling work, the technic of paraffin emulsion was study. At the same time, we study the effect from emulsification time,emulsification temperature,mix speed, viscidity liquid, surface active agent to paraffin emulsion. Test granularity of paraffin emulsion with laser granularity equipment. After that, the effect of drilling fluid’s density, filtration, HTHP filtration, rheology behavior, lubricate ability, inhibitive ability of the product has been evaluated.Experiments’ result express: This new product shows higher lubricate ability and inhibitive ability than the traditional one. With 2.5% capacity, the adhere factor reduction rate is 50% and shale hydration reduction rate is 28%.This paraffin emulsion exhibit excellent application effect. I could as a good drilling fluid agent in drilling .更多还原
